| Popis: | Populations of the sea urchin Evechinus chloroticus were monitored at wave-exposed low-sediment reefs and wave-sheltered high-sediment reefs in the Hauraki Gulf, northeastern New Zealand. Urchin populations on both wave-exposed and sheltered reefs were dominated by adults. Wave-exposed reefs supported higher densities (2.7 to 9.6 ind. m–2) than did wave-sheltered reefs (0.1 to 6.6 ind. m–2). Juvenile urchins ( |
